MERRY-GO-ROUND.

Application filed July 26, 1926, Serial No. 12,934p Renewed April 30, 1928.- i

My invention relates to improvements in merry go rounds.

It relates particularly to a type in WlllCll the riders provide the propelling power for the machine. I I

One of the objects of my invention is to provide a merry go round of the kind described With novel propelling mechanism by which the riders obtain the exercise and enjoy sensations similar to that to be had in rowing a boat.

A further object of my invention is the provision of novel means for rotatably supporting the device which carries seats for the riders, and which permits of the quick. and easy assembling or disassembling of the parts.

My invention provides further a novel construction which is simple, cheap, durable, strong, not liable to get out of order, and which is safe and efficient in its operation. The novel features of my invention are hereinafter fully described and claimed.

' My invention provides a rotary seat carrying device, comprising, preferably, two horizontal crossed beams 1 and 2, which are seats 3 at the outer ends respectively of said beams, Figs. 1 and 2. Y

serve as sweeps for supporting Extending vertically through the beams 1 and 2 at their place of intersection is a bearingtube provided adjacent to its lower end with a peripheral annular flange 5 which bears against the under side of the lower beam 2. Fitted on the tube 4 and resting against the upper side of the top'beam 1 is a collar 6. Vertical bolts 7 extend through the beams 1 and 2 and through the flange 5 and collar 6, whereby the beams are firmly fastened together, and are easily assembled and disassembled, see Fig. 3.

Extending upwardly into the tube 4: is a vertical spindle 8, similar to that used on an automobile, and having a peripheral flange 9 upon which run bearing rollers, such as balls 10, which are mounted in aball race provided in the lower end of the bear.- ing tubed, and which supportthe latter.

The inner side of the tube 41 has an annular race in which are mounted balls 11 which run upon the periphery of the spindle 8, and against a bearing collar 12 removably mounted on the threaded upper end of the spindle 8 and held injplace by a nut 13 on said spindle. The upper end of the tube 4: isthreaded and has fitted thereon a re- -movable hub cap 14. 3 I

For supporting the spindle 8, there is provided a cap 15 which is mounted on the upper end of a vertical-pipe 16, which is ''mounted at its lower portion in the ground, and which has init a filling, such as concrete 17 into which extends a stem 18 with which the lower portion of the spindle 8 is provided, said stem being removably mountedin the concrete and in a vertical central hole i'nthe cap 15. The latter may have threaded connection with the pipe 16, Fig. 8.

I will first describe the .preferred,em- ,bochment of my invention shown 1n Figs.

In order that the riders may propel the seat support formedby the fastened togetherr beams 1 and 2, there is provided concentrically on the pipe 16 a fixed bevel gear tate with four radial horizontal shafts '21.:

mounted in bearings 22, two pairs of which are fastened to. the under side of eachlbeam 1 and 2.

. The outer ends of the shafts 21 hav e respectively fastened to them bevel pinions 23, which respectively mesh with four bevel gear wheels 24, respectively fastened to and rotatable with four Vertical shafts 25, which respectively extend through and are rotatablelin four bearing tubes26, respectively mounted a pair in each beam 1 and 2, and provided with flanges respectively at their lower ends which bear against the adjacent beams. The upper end of each tube 26 threaded externally and has fitted on it a threadedcollar 2T whichbears on top of the djacent beam.

29 and respectively pivoted to the under sides of the levers 30, are four pawls 31,

obtained in rowing a boat.

which are respectively held engaged with the ratchet Wheels 29 by springs 32 respectively fastened to the operating levers 30, Fi 4.

.iteferring to v the form of propelling mechanism shown in Figs. 1 to 4, the riders,

occupying the seats 3, swing the levers 30 forwardly and draw them backwardly, as in rowing a boat. The pawls 31,'on the backward-movement of the levers 30 toward the riders in the adjacent seats, respectively engage the ratchet wheels 29, thereby revolving the vertical shafts 25. on their axes, and,

' through the intermediacy of the gear wheels 24, pinions 23, shafts2l, and pinions 20, effecting a revolving movement of the beams 1 and 2 in the direction indicated by the arrows in Fig. 1, due to the traveling engagement of the pinions 20 with the fixed gear wheel 19.

Swinging the operating levers, as described, givcs the operators of said levers an exercise and sensation similar to that For safe guarding the riders and their clothes from being injured by the gears 24 and pinions 23, housings 33 respectively en- 1 circling these sets of gears may be fastened to the under sides of the beams 1 and 2,.

Fig. 3. A similar housing 34 maybe fastenedto the under side of the beam 2 so as to encircle the gear 19 and pinions20, Figs.

. 2 and 3. I

Inthe modification, shown in Figs. 5 to 8, the beams 1 and 2, seats 3 carried there-' by, and the central'support on which the beams revolve, correspond in construction and mode of operation to the corresponding parts shown in Figs. 1 to 4, the difference inconstruction of the modification residing in the propelling mechanism. i a

In Figs. 5 to 8 portions only of the beams 1 and 2 and only one seat 3 are shown. A complete propelling unit embodying the modification is shown in these'iigures, of which the following is a description.' I

A vertical rock shaft 35 is oscillatively mounted in and extends through the carrying beam 2, and at its upper end is provided with a crank lever 36, which extends obliquely forwardly in front of the. adjacent seat 3. carried at the: right end of the beam 2.

Fastened to the lower end oftlie rock shaft 35 is a crank arm 37 to which is pivoted the outer end of asubstantially radial horizontal bar 38, the inner end of which is provided wit-h a pawl hook 39, which 'engages a ratchet wheel 40, whichis fixed and fastened to the pipe 16 in the place occupied by the gear wheel 19 in Fig.3, in the other form ofmy invention. ,1

lVhen the lever36 is oscillated, the crank forwardly,the bar 38 will be moved longi-- tudinally inwardly, thus causing the pawl hook 39 to slip over the ratchet teeth. When the lever 36 is again pulled rearwardly, the

bar 38 will again move outwardly and the pawl hook 39 will engage another tooth of. r the ratchet wheel'40. If the rider continues to oscillate the crank lever 36, the beams 1 and 2 and parts carried thereby will revolve, and the pawl hook. 39 willv travel around the rachet wheel 40. V c i The inner portion of the-bar 38 is supported by a bracket 41 secured to theunder side of the beam 2 and having a hole 42 through which the bar 38 extends andin which the bar is longitudinally slidable and laterally movable. 1

The pawl hook 39 is retained in operative engagement with the ratchet wheel 40' by means of a coil spring 43 one end-of which is fastened to the bar 38 and the other end of which is fastened to an upright plate 44 fastened to and depending from the "rear edge of the beam 2, Figs. 5 and. 6, the bar 38 being disposed forwardly ofsaid beam.

Two stop pins 45 and 46 maybe mounted in the bar 38 at opposite sides of and adapt ed to respectivelystrike the bracket 41 for limiting the longitudinal movement of the bar 38 inwardly and outwardly, Fig. 7. V

A collar 47 is fastened on the rock shaft and rests on the beam 2 for supporting said shaft. A collar 48 is fastened to the rock shaft 35 below said beam 2 for holding the rock shaft. from upward movement.

\ tures shown and described, as other modifications, within the scope of the appended claims, may be made without departing from the spirit of my invention.

What I claim is -1. In a merry go round, a central support,

a device rotatable thereon having a radial beam carrying a seat, a fixed gear wheel mounted on said support, a vertical shaft, a horizontal radial shaft, bearing means supporting said shafts on said beam, driving gearing connecting said shafts, a pinion mounted on and rotatable with the horizontal shaft, and adapted for travel on and meshing with said fixed gear Wheel, a ratchet wheel mounted on and rotatable with said vertical shaft, an operating lever oscillative on said vertical shaft adjacent to said seat and adapted for oscillation by a person occupying said seat, and a pawl carried by said lever and engaging said ratchet wheel.

2. In a merry go round, two crossed beams adapted to serve as sweeps for carrying seats, a vertical bearing tube extending through said beams at their place of intersection and having an annular peripheral flange bearing against the under side of the bottom beam, a collar on said tube bearing on the top of the upper beam, and fastening bolts extending through said beams and through said flange and said collar.

crossed beams adapted to serve as sweeps for carrying seats, a bearing tube extending vertically through said beams at their place of intersection and having an annular peripheral flange bearing against one of said beams,a collar on said tube bearing against the other beam, bolts extending through said beams and through said flange and said collar, a supporting spindle extending vertically into said tube, and bearing rollers carrying said tube and carried by said spindle.

In testimony whereof I have signed my name to this specification.
